4Grounding

Any CPE ODU must be installed with proper grounding Any CPE installation must have proper earth grounding at

customer home premises, so IDU relays on good grounding from electrical company

The AC should be tested and approved by our customer Avoid floating ground

For more detailed information please refer to the CPE installation manual - chapter 5

7Mounting kits

Pole mounting kit is provided with the unit The two pairs of threaded holes on the back of

the unit are enabling vertical and horizontal polarization

Use the washer then lock the nut Optional Tilt Mounting kit is available

Provides 15tilt range

Ver. 09-04-15

Provides 15tilt range Attached to the ODU and then to a pole

8ODU Polarization

Vertical Polarization

For vertical polarization install the unit with Polarization arrow pointing UP

For horizontal polarization install the unit with Polarization arrow pointing RIGHT

Ver. 09-04-15

Horizontal Polarization

9Connecting the antenna cable

Connect the right angle N-Type male connector of the coaxial RF cable to the antenna.

Connect the other end of the RF cable to the N-Type connector (marked ) located on the bottom panel of the unit

Fix the antenna cable onto the pole using a cable strip. Use additional cable strips to route the cable

such that water can accumulate on the cable

Ver. 09-04-15

such that water can accumulate on the cable bends, away from the unit.

When routing the cable, do not exceed the minimum bending radius in the cable specifications.

The RF connectors should be properly sealed to protect against rain and moisture

For more detailed information please refer to the CPE installation manual Chapter 6

Sealing ODU connectors

10SU IDU-ODU CAT5e Cable

SU IDU-ODU CAT5e Cable Indoor to outdoor Category 5 Ethernet cable with two

shielded RJ-45 connectors is used in order to connect the CPE unit to the outdoor

The length of the Ethernet cable connecting the CPE to the user's equipment, together with the length of the Indoor-to-Outdoor cable, should not exceed 100

Ver. 09-04-15

Indoor-to-Outdoor cable, should not exceed 100 meters/328 feet

In case of an external antenna installation, an additional RF cable with N-type connectors will be connected from the SU RF connector marked with to the antenna

The Indoor-to-Outdoor cable provides pin-to-pin connection on both ends

All eight pins are in use The drawing shows the wire pair connections required

for the Indoor-to-Outdoor cable

12Subscriber Unit IDU Installation

The unit can be placed on a desktop, rack or wall-mounted Drilling template included with the unit Assemble an RJ-45 connector with a protective cover Connect the IDU-ODU cable to the RADIO connector

Ver. 09-04-15

Connect the power cord to the units AC socket Verify that the POWER LED is lit Configure the basic parameters and align the antenna Connect the 10/100 Base-T ETHERNET connector to the data equipment Crossed Ethernet if connecting to a Hub/Switch Straight cable if connecting directly to a PC Network Interface Card

13Subscriber Antenna Alignment

DescriptionLED NumbersWireless link is up

Point the antenna towards the general direction of the Base Station Verify that at least one LED (LED 2) of the LINK QUALITY bar display is on,

indicated that the unit is synchronized with the AU Rotate the antenna until the maximum Link Quality reading is achieved Verify that the power indication of the unit is On

Seal the SAU connector For more detailed information please refer to the CPE installation manual Chapter 8

15SU Si Installation

Connect the Power

Verify that the Status LED is lit orange

If a detached antenna is used

Remove the cap on the top expose the RF connector

Connect to it the RF cable

Ver. 09-04-15

Install the antenna (as described in the following slides) Connect to it the other end of the RF cable

Fasten the antenna connector using the torque key

Connect the 10/100 Base-T ETHERNET connector to the data equipment

Crossed Ethernet if connecting to a hub/switch

Straight cable if connecting directly to a PC Network Interface Card (NIC)

Verify that the Ethernet Integrity Green LED is illuminating

16SU Si Installation

External antenna wall mount with pan capability - Indoor Installation Attach the suctions cups to the antenna

Place the antenna on the glass

the antenna connector should point downwards

press the suction cups onto the glass

Ver. 09-04-15

press the suction cups onto the glass

Connect the antenna cable to the antenna connector

Fasten the antenna connector using the torque key

Rotate the antenna left or right so the domed surface of the antenna is perpendicular to the direction of the Base Station

Check the Signal LEDs to ensure the antenna is aligned
